 If you liked Shaman King |  ...then you might like MÄR |
In these anime's, both characters call upon their respective spirits to do their bidding in battles which is to fight alongside with them. Weapons are used pertaining to the spirits that they own, and of course if you really approve or like tournaments then these anime's also had their own sets of battles for our heroes to fight in with the support of their teammates.
They have similar tones and themes storywise, and they are both well-written.
